Given: f(x)= x+ 7x + 12

and

g(x)= x+ 8x + 16

 

Find:

1.(f+g)(x) 

 

2.(f-g)(x) 

 

3.(f•g)(x)

1.(f+g)(x) = This is fairly simple, all you do is add the two problems.

x2 + 7x + 12 + x+ 8x + 16

2x2+15x+28

 

2.(f-g)(x) = Same thing here, just subtract the two equations.

x2 + 7x + 12 - x+ 8x + 16

-x-4

 

3.(f•g)(x) = 

x4+15x3+84x2+208x+192

 

4.(f/g)(x) = 

x+3/x+4

 

 

This is all combining like terms and simplifing. I highly recommend you use www.mathway.com to help you.

 

Hope this helps! Have a great day!!!
